Overview

allFilePaths is generated by computeUseDefinitions(). And in computeUseDefinitions, the path has been normalized.
But in finalizeFileResults.ts, we didn't normalize file dependencies. So the files alway marked as uncached that is a big problem.

// readFromCache.ts
for (const filePath of allFilePaths) {
	const fileCached = cached.get(filePath);
	if (!fileCached) {
		log("No cache available for: %s", filePath);
		markAsUncached(filePath);
		continue;
	}

LGTM with the caveat that if/when #2321 lands, we'll have to switch this to pathkey.
